I had my truck running while I installed a new socket for my trailer lights plug...when my screwdriver created a short between two of the contacts...the truck stalled. It started up fine after that...but now when I try to put it in reverse...it stalls every time. Should a short in the tail wiring cause the truck to stall ? I would expect a fuse to blow rather than a stall...is there a larger issue at play here ? Something is fishy !! This truck has the intermediate carb/fuel injection combo (cannot think of the name for that right now !). I think it may be called "throttle body" ?
